Nevada Alexander Musk (2002–2004)
Nevada Alexander Musk was Elon Musk’s first son, born in 2002 through his then‑wife Justine Wilson. The name followed Musk’s pattern of unconventional names, referencing both the U.S. state and a science fiction element. Tragically, Nevada died at approximately 10 weeks old due to sudden infant death syndrome. This loss influenced Musk’s public discussions on grief and family. Because he was born and passed in the early 2000s, Nevada does not appear in recent public announcements.
Kai, Saxon, and Griffin Musk
Kai Musk
Kai Musk, born in 2004, is the first son of Elon Musk and Justine Wilson. The name Kai has Maori origins, often meaning ‘food’ or ‘keeper,’ though Musk has not officially detailed the intended meaning. Little public information exists about his upbringing, as Musk has generally avoided extensive media coverage of his children’s personal lives. Kai has two younger full brothers born to the same parents.
Saxon Musk
Saxon Musk, born in 2006, is the second son of Musk and Wilson. The name Saxon may reference an English regional or historical naming tradition. As with his siblings, Musk has maintained privacy around Saxon’s activities. No official statements or verified photos have circulated widely in mainstream media, consistent with the couple’s approach during their marriage.
Griffin Musk
Griffin Musk, born in 2007, is the third son of Justine Wilson and Elon Musk. The name Griffin may draw from mythology or family preferences. Details about his early life remain sparse, reflecting the family’s low public profile during this period. Musk and Wilson divorced in 2008, and custody arrangements for the sons were not extensively disclosed.
X Æ A‑12 Musk
X Æ A‑12 Musk, born in 2021, is Elon Musk’s son with musician and producer Grimes (Claire Boucher). The birth was announced in May 2021, and the couple later clarified the pronunciation as ‘X Ash A Twelve.’ The name reflects a combination of influences: the X from Musk’s aerospace ventures, Æ from the elven alphabet in fantasy fiction, and A‑12 referencing the precursor aircraft to the SR‑71 Blackbird. This naming choice drew widespread media attention and prompted discussions about permissible character usage in California birth records. X Æ A‑12’s legal name has since been the subject of public and regulatory discourse.
Other Children and Context
In addition to his sons, Elon Musk has a daughter, Exa Dark Sideræl Musk, born in 2022 with Grimes. Musk has emphasized that he does not prioritize money as a primary parenting goal, though his net worth and resources are among the highest globally. Relationships and children have been intermittently visible in the press, but Musk tends to limit personal disclosures. The family’s dynamics span multiple partnerships, reflecting a blend of public prominence and private boundaries.
Conclusion
Elon Musk’s sons include Nevada Alexander (deceased), Kai, Saxon, and Griffin from his marriage to Justine Wilson, and X Æ A‑12 from his relationship with Grimes. Their names vary from conventional to highly unconventional, mirroring Musk’s distinctive approach to branding and personal identity. While some details remain private or unverified, the available public record provides a reliable foundation for understanding his fatherhood. This profile is designed to remain relevant and accurate over time, offering a clear reference for ongoing interest in Musk’s family.
